  • Applications

    Bis(3-aminopropyl)amine (CAS 56-18-8) is primarily used as a curing agent for epoxy resins in coatings and adhesives, and as a reactive intermediate and crosslinker for polymers such as polyurethanes and polyamides to enhance rigidity and thermal performance. It also serves as a building block for functional polymers and coatings, and can be employed as an intermediate to synthesize other functional compounds such as surfactants and chelating agents. Additionally, it may be used as a linking reagent or additive in the preparation of specialty polymers and electronic encapsulation materials, subject to local regulations and formulation limits.
